1.访问电子表格并收集相关数据。
2.使用适当的方程式(ODDO和TOMSON)在电子表格中计算秤饱和指数。
3. Run a sensitivity on pH.
4. Prepare charts showing the sensitivities.
5.与第1阶段相同的部分写一个简短的报告。您可以加入两个报告。
6. Give a conclusion on the scaling risk for calcite scaling and recommend a suitable course of action
Calcite Scale Model from Oddo & Tomson (1994) modified.
si = log(ca)(hco3)
+ pH -2。76
+ (9.88*10-3)T + (0.61*10-6)T2
- (3.03 *10-5)P
- (2.348 *(IS0.5) ) + (0.77*IS)
其中:Si是方解石(CA)和(HCO的饱和指数3) are the molar concentrations of Ca and HCO3ions in mol/L.
Ca的分子量为40,HCO3is 61.
T = temperature in degrees F
P = PSI的压力
IS = ionic strength of the produced water. This should be converted to mol/L by dividing by an average molecular weight (53.4) and converting to litre (outcome is to divide IS by 53400)
灵敏度Analysis: use the range of temperature and pressure shown on the Well Data worksheet to calculate the SI for a range of T, P and pH. Produce charts of these relationships.
Your report could include one or two pages of text and one page of tables and figures. The text should include the following:
Discussion : You may want to address the following in your discussion:
(a)解释定解量表的生产机制?
(b)描述饱和指数的相关性以及负值或正值的含义?
(c)您的评估主要局限性是什么?可以衡量什么?
(d) The well is scheduled as part of a large field development, what would you recommend to the Project Manager?
(e) When the well is in operation and producing, how would you monitor the process to ensure the scale risk was minimised.
