薛庄油田位于冀中坳陷饶阳凹陷东部潜山带,是一个中元古界蓟县系雾迷山组白云岩油藏。1977年9月马71井首次喷油发现油田,10月投入开发,到1978年又相继投入2口生产井,加上马71井放大生产压差提高采油量,至6月份油藏日产量达到了最高蜂,日产2000吨,折算年采油速度为26％。主力生产井马71井采用25毫米油嘴日产1856—1900吨,生产压差0.4兆帕,在无水生产的4个月中产量、压力稳定,到1978年9月马71井见水,产量由1850吨控制到800吨,整个油藏的采油速度由26％控制为15％左右,从此油藏进入含水采油阶段,日产油
Xuezhuang Oilfield is located in the buried hill belt in the eastern Raoyang Sag of the Jizhong Depression. It is a dolomite reservoir of the Wumishan Formation in the Middle Neoproterozoic Jixian Formation. In September 1977, the first oilfield was discovered in Ma 71 well. In October, it was put into development. In 1978, two production wells were successively put into operation. In addition, the production pressure of Ma 71 was increased to increase the oil production. By June, the daily oil production reached The highest bee, Nissan 2,000 tons, converted annual oil production rate of 26%. The main production wells Well 71 wells using 25 mm nipples 1856-1900 tons, the production pressure 0.4 MPa, 4-month anhydrous production in the production, pressure stability, in September 1978 to see the water wells Ma 71, the output from 1850 tons control to 800 tons, the entire reservoir production rate of 26% controlled by about 15%, from the reservoir into the oil recovery stage, Nissan
