南海北部湾涠10-3 18井是1990年8月投产的一口老油井.从1995年2月6日开始,用15.88mm油嘴稳定生产,日产原油185m~3,油气比939m~3/m~3.至1995年4月18日,已持续高产稳产70天,增产原油13268t,井口压力稳定为3.4MPa,日产原油180m~3土,成功地控制油气比为 485m~3/m~3.涠10-3-18井位于一个面积仅0.4km~3的半封闭式单独小断块中.两套油层厚达104m,控制石油地质储量103万t,至1994年底已累积产油207218t.日产原油量由初产1000t下降到
Beiwan Beiwan Bei 10-3 18 well was an old oil well put into operation in August 1990. From February 6, 1995, it was steadily produced with a 15.88mm nozzle, with a daily oil output of 185m ~ 3 and an oil-gas ratio of 939m ~ 3 / m ~ 3. As of April 18, 1995, the high-yielding and stable production has been sustained for 70 days with an increase of 13,268 tons of crude oil, a pressure of wellhead stability of 3.4 MPa and a daily crude oil production of 180m-3 so that the oil-gas ratio can be successfully controlled at 485m 3 / m 3. Well 10-3-18 was located in a semi-enclosed, small block with an area of only 0.4 km ~ 3. The two oil reservoirs were as thick as 104 m with a controlled oil geological reserve of 1.03 million t and had produced 207,218 t of oil by the end of 1994.
