Current Status and Developing Direction of Acidizing Techniques for Horizontal Wells in Luojiazhai Gas Field with High Sulfur Content

Acidizing techniques for horizontal wells is one of the major technical problems for oil production test of horizontal wells in Luojiazhai gas field. With long-time practice and continuous study, a set of mature acidizing techniques for horizontal wells have been developed by Down-hole Service Com. of Sichuan Petroleum Administration. But they still need to be improved. The article introduces the current status of acidizing techniques for horizontal wells in Luojiazhai gas field with high sulfur content. Aiming at the characteristics of high sulfur content of the gas field and the technical problems of horizontal well acidizing, the main technical issues to study and solve in the future are proposed, which have important guiding effect for Luojiazhai gas field with high sulfur content to increase production of acidized horizontal wells.
