甲酸鉀是鉆井液用中主要的有機(jī)鹽

鉆井液用有機(jī)鹽主要為甲酸鹽,甲酸鉀鉆井液體系在國(guó)外己被廣泛應(yīng)用,均取得很好的效果,甲酸鉀鉆井液的特點(diǎn)歸納在下面,可以供參考:
The organic salt used in drilling fluid is mainly formate. Potassium formate drilling fluid system has been widely used abroad and has achieved good results. The characteristics of potassium formate drilling fluid are summarized below for reference:
(1)與地層水接觸時(shí)不會(huì)形成沉淀物,對(duì)儲(chǔ)層損害程度低;
(1) When contacting with formation water, sediment will not be formed, and the degree of damage to the reservoir is low;
(2)生物毒性非常低,對(duì)人體無害,對(duì)水生物群落影響很小,生物富集性??;
(2) The biological toxicity is very low, harmless and non-toxic to human body, with little impact on aquatic biological communities and low bioaccumulation;
(3)可生物降解,不污染環(huán)境,并且可回收,可重復(fù)利用;
(3) Biodegradable, non polluting, recyclable and reusable;
(4)可為鉆井完井液提供適當(dāng)?shù)拿芏?,不需要固體加重劑,容易實(shí)現(xiàn)無固相鉆進(jìn)或低固相鉆進(jìn);
(4) It can provide proper density for drilling and completion fluid without solid weighting agent, and it is easy to realize solid-free drilling or low solid-state drilling;
(5)甲酸鉀鉆井液pH值容易調(diào)節(jié),對(duì)金屬、橡膠等腐蝕性小;
(5) The pH value of potassium formate drilling fluid is easy to adjust and has little corrosion to metals, rubber, etc;
(6)循環(huán)壓降小,易于配置,維護(hù)簡(jiǎn)單;
(6) Small circulating pressure drop, easy configuration and simple maintenance;
(7)粘度低,流動(dòng)性好,摩阻壓力損失小,適用于小井眼和易漏失地層鉆進(jìn);
(7) Low viscosity, good fluidity, low friction pressure loss, suitable for drilling in slim holes and formations prone to leakage;
(8)抑制性強(qiáng),井壁穩(wěn)定,井徑規(guī)則。
(8) Strong inhibition, stable shaft wall, regular well diameter.
在國(guó)內(nèi)采用CH3COOK和K3PO4取代KCl作為抑制劑而形成的無氯新甲酸鉀鉆井液體系,先后應(yīng)用于東部地區(qū)且收效明顯。鉆井液體系復(fù)配,成功地應(yīng)用在莊海4x1井,實(shí)現(xiàn)了低毒、、防塌、抑制性強(qiáng)、保護(hù)儲(chǔ)氣層等性能。
In China, the chlorine free potassium neoformate drilling fluid system formed by using ch3cook and K3PO4 to replace KCl as inhibitors has been successively applied in the eastern region with obvious results. The drilling fluid system has been successfully applied in Zhuanghai 4x1 well, achieving high-quality performance such as low toxicity, high efficiency, collapse prevention, strong inhibition and gas reservoir protection.
