辽河油田曙一区七排五块大凌河油层,原油比重大、粘度高,属特重油,长期未投入开采。1983年吞吐试验地质方案实施以米,已经有两口井获得高产,初期自喷最高日产油量分别为152方和175.6方,平均日产油量分别为106.4方和96.8方。该块的大凌河稠油层于1976年2月就已经发现,尽管油层厚达114米,但是油质太稠(地面脱气原汕粘度30000—40000厘泊),在一般工艺水平条件下,无法获得工业性产能,常规试油结果不出油。经过挤轻质油和酸化等措施后洗井,累积出油仪30升,无工业价值。
Liaohe Oilfield Shu an area seven rows of five Dalinghe oil, large proportion of crude oil, high viscosity, is a special heavy oil, long-term not put into mining. In 1983, the throughput test geology program was implemented in rice. Two wells have been obtained with high yield. The maximum daily initial production was 152 square meters and 175.6 square meters respectively. The average daily oil production was 106.4 square meters and 96.8 square meters respectively. The Dalinghe heavy oil reservoir of this block had been discovered in February 1976, and despite the fact that the oil layer was 114 meters thick, the oiliness was too thick (the ground viscosity was 30,000-40,000 centipoise). Under the conditions of general technological level, Unable to obtain industrial capacity, conventional oil test results do not oil. After crowding light oil and acidizing measures such as washing wells, accumulator out of 30 liters, no industrial value.
