The Sa-erh-tu, Ko-la-ma-i, and Kuang-jao oil fields are the three
largest producing fields in China. The Sa-erh-tu field consists of
approximately 183,000 acres and 4,600 well sites/oil wells; Ko-la-ma-i
approximately 95,000 acres and 2,050 well sites/oil wells; and Kuang-jao
approximately 31,000 acres and 720 well sites/oil wells. The fields were
discovered in the late 1950's-early 1960's, but the greatest development
did not occur until the 1966 to 1968 period. They appear to have been
systematically developed with well spacing on a regular pattern, which is
a conservation practice used to exploit a field to its fullest capacity.
Exploratory drilling locations observed in these fields suggest that the
fields will be expanded in the future.
The Yu-chuan-tzu field consists of approximately 512 acres with at
least 32 well sites/oil wells, and the Yu-sha-shan field consists of about
74 acres containing an undetermined number of well sites/oil wells. These
two fields were first studied on photography of 1961 and remained relatively
undeveloped through November 1968 with only minor expansion at Yu-sha-shan
between 1966 and 1968.
This report includes an annotated photograph, mensuration of signifi-
cant features, a chronology of expansion, and the current status of each
field.

The Sa-erh-tu Oil Field surrounds the town of Sa-erh-tu on the Sung-
liao Plain in Heilungkiang Province. The field is served by spurs from
the Ha-erh-pin to Chi-chi-ha-erh rail line. No major roads enter the area,
but the field has an internal road network.
The Sa-erh-tu Petroleum Refinery and Storage) I a thermal
power plant, a possible oil processing plant, and a possible petrochemical
plant are associated with the operation. A portion of the crude oil ex-
tracted is refined at the Sa-erh-tu petroleum refinery, and the excess is
shipped by rail to refinery facilities in eastern China.
Physical Features
The oil field measures approximately 28 by 10 nm along a major north-
south axis and contains approximately 183,000 acres. Approximately 4,600
well sites/ Py"ratory drilling rigs were identified on
photography The field was developed utilizing a 40-
acre well spacing pattern. A total of 103 storage tanks are located in
the field, at the associated plants, and the rail loading facilities
(see Table I).
Chronology
When first observed on photography ofl Ithe field
consisted of approximately 780 well sites/oil wells located on about 32,000
acres. It developed slowly between 1961 and 1966 with an average of 250
well sites/oil wells being added per The rate increased to 1-300 nPW
well sites/oil wells per year between
The field gathering system and its associated storage tanks have been
Continually expanded with the development of the field.

The Kuang-jao Oil Field surrounds the town of To-chia-chuang on the
northeastern edge of the Sheng-li Basin in Shantung Province. No major
roads or rail lines serve the area; however, the field has an internal road
network. The crude oil is piped from the field to a pipeline terminal at
Yung-liu-chuang (36-48N 118-13E), a distance of 54 nm. From there it is
shipped by rail to Ching-tao, where it is transloaded to tankers for ship-
ment to the Nan-ching Petroleum Refinery
Physical Features
The oil field measures approximately 8 by 8 nm and contains approxi-
mately 31,000 acres. Approximately 720 well sites/oil wells and 12 ex-
The field was developed utilizing a 40-acre well spacing pattern. A total

ploratory drilling rigs were identified on photography of
Chronology
When first observed on photography ofl I the field consisted
of about 11,000 acres. At that time only preliminary work, such as sur-
veying and construction of gathering tanks, was under way. Exploratory
wells were probably being drilled at that time, but could not be discerned
on the small-scale photography. The field developed slowly between 1965
and 1966, increasing to about 14,000 acres with the number of well sites/
oil wells increasing from 19 to 49 locations. Between 1966 and 1967 the
field expanded to 193 locations and doubled in area. By September 1968
the well spacing pattern had changed from 60 to 40 acres per site, resulting
in an increased number of wells. Approximately 720 well sites/oil wells
were identifiable in the approximate 31,000 acre area.

The Ko-la-ma-i Oil Field is located in the vicinity of Ko-la-ma-i on
the northwestern edge of the Dzungarian Basin in Sinkiang Uighur Autonomous
Region. The Ko-la-ma-i Airfield and the Ko-la-ma-i Petro-
leum Refinery are respectively located west and south of
the oil field center. No rail facilities service this area, but a well
maintained, all-weather road connects Ko-la-ma-i with Tu-shan-tzu to the
south. A portion of the crude oil extracted is processed at the Ko-la-ma-i
Petroleum Refinery and the excess is shipped via pipeline to the Tu-shan-
tzu Petroleum Refinery Here it is transloaded and carried
by rail to the Lan-chou Petroleum Refinery
Physical Features
The oil field is elongated in a northeast/southwest direction. Three
pools could be identified within the field on photography of
Pool A, the northernmost, is generally circular in plan with a
lame er of approximately II nm. It contains about 51,000 acres and 32
randomly spaced well sites/oil wells. Pool B, the southernmost, measures
approximately 6 by I nm. It contains about 4,550 acres and 21 randomly
spaced well sites/oil wells. Pool C, in the center, is crescent shaped
with a 17 nm long axis and a 4 nm maximum width. It contains approximately
40,000 acres, 1,995 well sites/oil wells, and five exploratory drilling
locations. It was developed utilizing a 20-acre well spacing pattern.
A "central jack" pumping system was identified at this pool. This type
of system is usually associated with shallow production in the United
States. A total of 66 storage tanks are located in the field (see Table
Table 111).
Chronology
When first observed on photography of 30 May 1962, the field consisted
of about 47,000 acres in Pool A, 4,550 acres in Pool B, and 14,000 acres
in Pool C. Only minor development in Pools A and B was noted from 1962
through 1968. However, Pool C developed rapidly, doubling in size between
1962 and 1965, and increasing to three times its original size by 1968.
Since May 1962, the date of the earliest good-quality photography over the
area, the average rate of expansion in Pool C has been 200 well sites/oil
wells per year.

The Yu-chuan-tzu Oil Field is located approximately 1.5 nm east-
southeast of the town of Yu-sha-shan on the western edge of the Tsaidam
Basin in Tsinghai Province. A railroad has not been built into the area,
but a well maintained road goes from Yu-sha-shan to Hung-ang-chuan. The
crude oil from this field is probably shipped by truck to t
he Pai-yang-ho
Petroleum Refinery, Yu-men
and then by rail
to the Lan-chou
25X1

northwest axis and contains approximately 512 acres. At least 32 well
sites/oil wells were identified on photography of These 25X1
well sites/oil wells tend to reflect a 20-acre well spacing pattern. A
total of II storage reservoirs are located at the field (see Table IV).

town of Yu-sha-shan on the western edge of the Tsaidam Basin in Tsinghai
Province. A railroad has not been built into the area, but the field is
served by a trail off the road between Yu-sha-shan and Hung-ang-chuan.

BASIC DESCRIPTION
Physical Features
25X1
25X1
The oil field measures approximately 0.7 by 0.2 nm along a west-
northwest/east-southeast axis and contains approximately 74 acres. An
undetermined number of well sites/oil wells existed in the field on
photography of Because of the rugged topography and 25X1
small scale of available photography, it is not possible to give a more
detailed analysis of the facilities and equipment here.
Chronology
The field was first observed on photography o and
subsequent coverage through February 1966 revealed no evidence of expansion.
Between February 1966 and November 1968, the field had expanded from 52 to
74 acres.
