石油设备网讯 据World Oil网休斯顿4月17日消息 法国石油公司道达尔的目标是扩大桑托斯盆地盐下油田的产量。
道达尔称拉帕计划于今年在桑托斯盆地盐层下进行新的开发活动，其中包括在该地区钻4口井。据该公司介绍，该工程将允许增加有担保资产的产量。
Campo de Lapa现在通过连接到FPSO Cidade de Caraguatatuba的两口油井，每天生产约2.4万桶原油。与巴西国家石油公司谈判后，道达尔公司于2018年1月接管了油田，目前的产量比2018年1月的产量低40%。
上周，法国石油公司完成了对LPA-1D拉帕油井之一的干预行动。该工程于2月展开，包括缓冲油井、隔离地面储层以及安装水下设备。
据报道，由于低压和高压壳体的分离，LPA-1D在海床上方有一个斜坡。尽管斜坡并没有破坏安全屏障，但石油公司决定在永久放弃油井之前停止生产。
道达尔表示:“目前公司与主管部门及其在拉帕财团中的合作伙伴合作，成功地实施了这一干预。”
作为一项预防措施，ANP已授权关闭注入井，以避免在干预期间井内压力增加。据该机构称，这些油井已经开始再次运转。

Total plans four new wells in Lapa field, offshore Brazil
The objective of the French oil company is to expand the production of the field in the pre-salt of the Santos Basin.
Scheduled this year, Lapa's new development campaign in the Santos Basin pre-salt will include drilling four wells in the field, Total told BE Petróleo. According to the company, the works will allow to increase the production of the asset with security.
Campo de Lapa now produces approximately 24,000 bopd from two producing wells connected to the FPSO Cidade de Caraguatatuba. The volume is 40% lower than the one extracted in January 2018, when Total took over the field operation, after negotiating with Petrobras.
Last week, the French oil company completed an intervention campaign in one of the LPA-1D's Lapa wells. Initiated in February, the works consisted in buffering the well, isolating the surface reservoir, and installing underwater equipment (manifold and treecap).
As reported by BE Petróleo, the LPA-1D had a slope above the seabed due to the decoupling of the low and high pressure housings. Although the slope did not compromise safety barriers, the oil company decided to stop the production of the well before abandoning it permanently.
"Total worked with the competent authorities and its partners in the Lapa consortium to carry out this intervention in a successful way," the company said.
As a preventive measure, the ANP had authorized the shutdown of the injector wells in order to avoid increase of pressure in the well during the intervention. According to the agency, these wells have already started to operate again.
