Plugging mechanism and prediction of asphaltene in Bashituo Oilfield

Yakela Gas Production Plant, SINOPEC Northwest Company, Kuqa, Xinjiang 842017, China

摘要: 巴什托油田生产过程中,"堵塞"现象一直伴随着生产存在,严重影响生产及油气开发.分析认为原油内部胶体不稳定,地层及井筒压降是导致沥青质沉淀堵塞井筒的主要原因.通过压力推导预测沥青质析出深度基本分布在500~2 400 m之间,在生产过程中,对该井段着重进行机械除垢,从而达到预防井筒堵塞的目的.

Abstract: "Wellbore plugging" phenomenon, which always accompanies the whole production cycle, has seriously affected oil and gas production and reservoir exploitation in the Bashituo Oilfield. Colloid instability of internal oil, formation, and pressure drop are the main reasons for asphaltene precipitation and wellbore plugging. By pressure derivation, the predicted depth of asphaltene precipitation ranges from 500 to 2 400 m. Mechanical descaling focused on these sections during production process can successfully help to achieve the purpose of wellbore plugging prevention.
